To all whom it may concern Be it known that we, Moens MOSLER, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, and CARL BARTELS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Safe Construction, of which the following is a specification.

This invention, pertaining to safe construction, relates to the manner of constructing the stepped door-jambe and the stepped door-frames of fire-proof safes. In this connection it should be explained that in using the term door-frame we mean the frame that margins and forms a part of the door itself as distinguished from the similar term employed in architecture as meaning the stationary frame into which the door closes. This stationary frame into which the door closes we denominate the doorjamb. In the most usual manner of constructing the stepped door-frames and doorjambs of fireproof safes these parts have been made each of an integral casting. They are liable to breakage in handling and in process of utilization, and they are liable to warpage, which warpage could not be rectiied by straightening and, owing to the exigencies of the production of iron castings they could not be as nicely fitted to each other as was desirable. It has been pro posed to form the stepped door-frames and door-jambs of wrought metal bars, properly rolled or otherwise shaped, and to oin these lbars at the corners by means of angle patches riveted to them, the patches being riveted inside the door-frame and outside the door-jamb so that the exterior of the door-frame could properly fit the interior of the door-j amb without interference from the patches employed in forming the corner joints. Such construction possessed the disadvantage of added cost due to the corner patches and to the applying of them, and also possessed the disadvantage of the lack of integrality in the structures.

We have heretofore invented a plan for forming these parts by taking bars of stepped cross-section and cutting them to miters and then, after securing the bars in proper relationship to each other by suitable clamping means, welding the mitered joints by autogeneous welding. This was a vast improvement over previously known methods for constructing the stated parts but it involved the disadvantage due to the necessity of accurately positioning the separate bars before the joints were welded.

In our present invention we form doorframes and door-jambe of wrought metal of stepped cross-section, but we avoid the necessity for the employment of riveted corner angles, and we also avoid the necessity for clamping the several bars in relation to each other while the joints at the corners are being welded by the autogeneous method.

Our present invention will be readily understood from the following description taken in connection with the accompanying drawings in which Figure 1 is a front elevation of a doorjamb, with a portion of the door-frame seated within it, both being constructed in accordance with our present invention; Fig. 2 a front elevation of the bar, of stepped cross-section, of which our door-jamb is formed, the drawing showing the bar as having been transversely cut to permit of its being bent to desired form, and showing one of the side bars of the jamb bent from the balance of the bar; Fig. 3 a front elevation of one of the corners of the bent stepped bar forming the door-jamb; Fig. ai a crosssection of the stepped bar forming the doorjamb in connection with the stepped bar forming the door-frame, the cross-section being taken, for instance, on the line a of Figs. 1, 2 and 3; Fig. 5 a front elevation of one of the corner blocks to be welded into the bent corner of the door-jamb in case the door-jamb is to be provided with a socket for the reception of a lug upon the door frame: Fig. 6 a front elevation of a similar corner block to be welded into the bent corner of the door-jamb in case no socket is to be provided, Fig. l showing the general structure as being provided with lug-sockets at the two upper corners, and with plain mitered joints at the lower corners: Fig. 7 a perspective view of the corner block of Fig. 5: Fig. 8 a perspective view of the corner block of Fig. 6: Fig. 9 a perspective view of one of the corner blocks of the door frame, the same carrying a lug to enter the socket of the corner block of the door-jamb: and Fig. l0 a perspective view of one of the corner blocks of the door frame to coperate with such corner-blocks of the door-jamb as are illustrated in Figs. 6 and V8. A

In the draWings:-1, indicates the rectangular door-jamb, of stepped cross-section, as is usual in the door-jambs of fire- `proof safes: 2, the upper member of the door-jamb 3, one of the side members; 4, the lower member: 5, the second side member: 6, the innermost portion of the doorjamb: 7, open corners resulting from the cutting and bending of the bar from which the door-jamb is formed: 8, the corner blocks Welded into the open corners of the door-jamb at those corners Which are to be provided With lug-sockets: 9, the cornerblocks to be Welded into the open corners of the door-jamb at those points Where the joints are to be plain miters instead of socketed: 10, the sockets in the socketed cornerblocks of the door-jamb: 11, the lines of Welded juncture between the corner-blocks andthe bars forming the door-j amb: 12, the stepped door-frame, fitting the door-jamb and formedV With open corners in the same manner as the door-jamb: 13, thecornerblocks Welded into such of the open corners of the door-frame as are to have lugs to engage sockets of the door-jamb: 14, the lugs on the rear of these corner-blocks to properly enter Vthe sockets 10 of the doorjamb: 15, the corner-blocks Welded into such of the open corners of the door-frame as are to be united by plain mitered joints instead of being provided with lugs: 16, the lines of Welded juncture between the main bars and corner-blocks of the door-frame: and 17, the cross-cuts made in all of the outer members of the stepped bar from Which the door-jamb and door-frame arev to be made, these cross-cuts not cutting into the inner member 6 of the door-jamb or the corresponding member of the door-frame.

Looking at the method of production of the door-jamb and disregarding for the present the door-frame, a bar of stepped cross-section, vrolled vor otherwise formed to proper shape, and preferably of sufficient length to form the four margins of the door-jamb, is cross-cut vat the points which are to be at the corners of the jamb, as at 17 in Fig. 2. These cross-cuts go through the outer stepped members of the bar but do not go into the inner member 6. The bar in this cross-cut condition is illustrated in Fig. 2. The bar is then bent, the bending taking place only on the uncut inner portion 6 of the bar, into the rectangular form, one of the bends being illustrated at the left of Fig. 2. v The result is an integral rectangular jamb with open corners 7. The open corners of the jamb are then lled in by means of corner-blocks presenting to the cut ends of the bar a corresponding cross-sec- Copiel of this patent may be obtained for ve cents each, by addressing 'the Commissioner of YPatents,

ltion, these corner-blocks being Aeither of plain mitered characteror socketed character as desired, socketed blocks being illustrated in the upper portion of Fig. 1, and in Figs. 5 and 7, While plain blocks are illustrated'at the loWer portion of Fig. 1` and rin Figs. 6 and 8. These corner-blocks having been located they are Welded to the straight members of the jamb by autogenic process, the result of which is that the jamb With its corner blocks forms a complete integral structure of Wrought metal of accurate crosssection vthroughout the interior perimeter of the jamb. Such a door-jamb can be accurately and economically formed and is not liableV to breakageY inV subsequent utilization in safe construction. Such a door-jamb forms the female element of a jamb of the door couple and is adapted to receive a door-frame of any appropriate and suitable form. But We provide for constructing the door-frame, ythe maleV element of the couple, in the same manner as has been set forth for the door-jamb, the only difference being that the door-frame is small enough to fit Within the door-jamb and that the cornerblocks of the door-frame, if the general structure involves the lug and socket construction, is provided With lugs instead of sockets.

By taking a bar, such is is illustrated in Fig. 2, of sufficient length nto form the four margins of a jamb or door-frame tovbe produced, Welding is required Aonly at the corners of the rectangle formed by bending the bar, and, after the bar is bent, the four margins, are self-positioning or held in proper relationship With each other. But, instead of forming the rectangle of a single bar of suiiicient length, shorter bars may` be employed and united by other autogeneous Welds, the bending at the corners still being retained. v

We claim A In safe-construction the method for the production of stepped door-jambs or stepped door-frames which consists in taking a bar of stepped cross-section, crosscutting the bar in such manner as to leave uncut that portion of the bar Which isV to form the inner member of the article, bending the bar so as to produce an open corner at the cross-cut, disposing in said open corner a corner-block forming cross-sectional continuations of the cut portions of the bar, and autogeneously Welding the corner-block to the cut ends of the bar, combined substantially as and for the purpose set forth.
